Package: hw-detect
Version: 1.54
Severity: wishlist
Tags: patch

Hi,
the attached patch adds detection of I/O multipaths to disk-detect. This
has to be enabled by using disk-detect/multipath/enable=true and is
modeled after the dmraid code. If multipaths are found it pulls in the
partman-multipath udeb so the paths can be properly partitioned.
Please apply,
 -- Guido

Changes: 
 hw-detect (1.60) unstable; urgency=low
 .
   [ Guido Guenther ]
   * Add optional multipath detection to disk-detect.sh (triggered by
     disk-detect/multipath/enable). Closes: #440439.
 .
   [ Frans Pop ]
   * Some older systems have a disk controller that is not listed by lspci,
     but that is supported by ide-generic. Load ide-generic if an ISA bus is
     detected and, if new block devices become available, register the module
     for inclusion in the initrd. Closes: #472487.
   * hw-detect: simplify is_available() function.
